I made the change from three to four screws, but you're able to edit the guides as well. If you want to edit something, you can click the Edit link on the right side of any guide step, or the Edit link at the top right of the page (sandwiched in-between View and History).

It's time to speak out for your right to repair

We have a chance to guarantee our right to repair electronic
equipment—like smartphones, computers, and even farm equipment. This is a once-in-a-generation
chance to protect local repair jobs—the corner mom-and-pop repair shops that
keep getting squeezed out by manufacturers.

Join the cause and tell your state representative to support Right to Repair. Tell them you believe repair should be fair, affordable, and accessible. Stand up for your right to repair!
